BALE AND LIKE TRANSPORTER.

Specification of Letters Patent.

Patented July 12, 1910.

Application filed November 20, 1908. Serial No. 463,690.

To all whom it may concern:

Be it known that we, ALBERT WINCKLER and CHARLES WINGKLER, citizens ofthe French Republic, residing at Lyon, in France, have invented certainnew and use ful Improvements in Bale and Like Transporters, of which thefollowing is a specification.

This invention relates to transporters intended for the conveyance ofcases, bales, packages and the like of average dimensions in factoriesor warehouses and for loading or unloading the same on to or from wagonsor trucks.

It essentially comprises under varying forms of construction two or moresprocket or like chains moved parallel to one another in a horizontal orinclined plane according to circumstances on which chains the pack agesto be conveyed are placed. Automatic mechanism arrests the movement ofthe chains when a package arrives at the end of the apparatus or at anyother point previously determined.

The apparatus usually comprises three main parts viz: the unloader, theconveyers and the loader; the annexed drawing shows 'the generalarrangement of these parts.

Figures 1 and 2 represent an unloader in elevation and planrespectively. Figs. 3 and 4 are similar views of a conveyer and Figs. 5and 6 are also similar views of a loader.

In the unloader shown in Figs. 1 and 2 the upper surfaces of theparallel chains on a which receive the goods to be conveyed are disposedin inclined planes and receive on their elevated part the packages froma truck or wagon and conduct them to the level of the conveyers, thislevel being arranged at that most suitable for manipulation. The twochains a a are each carried at opposite ends of the apparatus by twotoothed wheels h h keyed on shafts j and their upper surfaces are guidedin bars I) of trough section above which they project in order that saidchains may support the goods being handled. The bars or guides b aresupported and maintained at the desired distance apart by a framing b ofsuitable construction mounted on wheels 00 which permit of moving theentire unloader to the proper distance relatively to the wagon to beunloaded.

Movement is imparted to the chains by an electric motor d driving bymeans of a belt f a suitable speed reducing gear inclosed in a casing rand comprising a worm emeshing with a worm wheel 9. -On the shaft of thelatter is keyed a sprocket wheel 2' about which passes one of the chainsa so as to be driven thereby, the other chain being correspondinglydriven through the shafts j.

The movement of the chains may be arrested by mechanism consisting of arod is by means of which the belt f can be shifted on to a loose pulleyf said strap f being normally held on a fixed pulley f by a spring Zattached to a lever 70, which actuates the rod is. At its upper end thelever la is connected by a draw rod m to a lever 0r abutment n pivotedat 0, said abutment being arranged between the chains a at the forwardend of the apparatus, so that the goods being conveyed make contact withsame, whereby the abutment is forced forward and puts the drivingmechanism out of action. The movement of the chains is thus arrested andconsequently all the goods conveyed thereby until the package causingsuch stoppage has been removed whereupon the belt f will be again movedon to the fixed pulley f by the spring Z and the movement of the chainswill be resumed.

The goods removed from the lower end of the unloader are placed ondifferent conveyers which conduct them direct to the desired points inthe warehouse.

The conveyers shown in Figs. 3 and 4 are of difierent lengths and ofsuflicient number to serve the different parts or departments of thewarehouse or depot where they are in use. The said conveyers areconstructed on the same principle as the unloader with the exceptionthat their upper surface is horizontal and disposed at such a height asis most suitable for convenient handling in front of the unloader inorder that the goods may pass easily from one to the other. Theconveyers are usually stationary, their chains a a are put in movementsimilarly to those of the unloader, by an electric motor (Z driving bymeans of belt 7 a speed reducing gear contained in a casing T which gearactuates one of the chains. The belt i is put out of action on to aloose pulley f by the abutment a when a package comes in contacttherewith, the belt being again shifted on to a fixed pulley f by aspring Z and intermediate mechanism when the package is removed from theconveyer.

The loader shown in Figs. 5 and 6 is arranged in continuation of aconveyer T arranged as previously described and extended by a movableextension A pivoted on a horizontal shaft 79 rotating in bearings qfixed to the end of the conveyer. The said shaft p is rotated by themotor (Z by means of a speed reducing gear contained within a casing 1and amovable strap f On the shaft p are keyed two sprocket wheels 8 8driving the chains (1 a of the conveyer. At the center of the shaft 79is keyed a sprocket wheel t adapted to drive the wheel 0 by means of thechain a, said wheel a, being keyed to a shaft a; at the forward end ofthe loader. On the said shaft w are keyed two other wheels 4) 1) drivingthe two lateral chains 11 u passing at the opposite end around thewheels t t freely rotatable on the shaft 29. The chains u it serve toconvey the packages along the loader. The forward end of the extension amay be raised by means of two chains or ropes z 2, so that it can bebrought to a convenient height for loading, said chains .2 beingoperated by means of a winch or other suitable device (not shown).

The packages fed along by the conveyer T pass on to the extension Aalong which they are moved by the chains it until they meet the abutment3 which by means of the rod 1, angle lever 2, rod 3, and angle lever 4:acts on the belt shifting rod 5 drawn back by the spring Z and arreststhe movement of the chains until the package has been removed. So longas the extension A remains in a horizontal or only slightly inclinedposition the abutment e actuates the belt shifting mechanism alone butwhen said exten sion is in a more inclined position it is necessary toarrest the packages before they reach the extension which they would notbe able to mount; in this case a second abutment 6 is arranged near theend of the conveyer and arranged so as to be clear of the packages andallow them to pass on to the extension as is shown in full lines in Fig.5 while it is caused to rise into active position when the extension israised to such an extent that it cannot be mounted by the packages. Thisresult is obtained by a rod 7 connecting the lever 8 to a pivotal point9 on the end of the extension the position of the point being such thatwith a moderate inclination of the extension the lever 8 will not beefiectively displaced, while it is drawn back by the rod 7 when greaterinclination of the extension takes place.

The lever 8 is keyed on a shaft 10 on which is mounted the abutment 6 bymeans of a parallelogram 12 which supports it in a vertical positioncausing it to assume the position 6 shown in broken lines when theextension is raised and it then acts on the belt shifting mechanism bymeans of a rod 11 when it is engaged by a package.

It will be understood that the arrangements hereinbefore described canbe varied according to requirements, the various apparatus can also bemovable as in Fig. 1 or fixed as in Figs. 3 and 5, and the movingelements thereof can be actuated by motors of any kind, or by belts orother transmission mechanism.
